ICP Furnace Control Board for RGS102LEAB0AAA — OEM Kit 1183618 | Ships Today

Overview

This is a genuine OEM integrated furnace control board kit (part number 1183618) for the ICP / Heil / Tempstar RGS102LEAB0AAA gas furnace. The control board is the brain of the furnace — it sequences the inducer, hot surface igniter, gas valve, and blower motor, monitors safety circuits, and provides diagnostic flash codes. When the board fails, the furnace may not respond to a heat call, may run blower-only, or may flash repeated fault codes. The kit ships with mounting hardware and instructions for a complete replacement.
